In 57 infants and very young children, less than 2 yr of age and with a variety of cardiopulmonary illnesses, problems were encountered in the estimation of lung volume with the plethysmographic technique. In 19 subjects calculated thoracic gas volume (TGV) was found to be consistently larger when airway occlusions were performed at low lung volumes than when performed at higher lung volumes. In 13 infants, changes in intraesophageal pressure (Pes) during airway occlusions were found to be… CONTINUE READING
